Name of Waterfall

Lillian Falls

Description

Rocky Run Creek originates in Lake Lillian on the south end of Rampart Ridge. Exiting the lake the stream flumes down a narrow crack, cascading a total of 253 feet before flowing through a talus pile. Almost immediately after it drops over another fall of 35 feet before emptying into small but quaint Lake Laura. Though the falls are fairly visible from around Lake Laura, because the majority of the drop occurs within a narrow crack in the cliff band the upper reaches of the falls are difficult to see clearly.
Rocky Run Creek at this point in its course is entirely dependent on snow melt for sustenance and though the small basin above Lake Lillian retains a significant amount of snow into July, once the snow has disappeared the lake level will drop enough that the falls will often dry out entirely (generally by September) until wet weather returns in the fall.
